GUSTAV IIILGENSTOOK, OF DAHLI-IAUSEN-ON-TIIE-ItUHR, GERMANY, AS- SIGNOR TO THE UNITED COKE AND GAS COMPANY, OF CHARLESTON, IV 3ST VIRGINIA, AND PHILADELPHIA, PENNSYLVANIA.

C O K E O V E N SPECIFICATION forming part of Letters Patent No. 649,450, dated Mav- 1 5, 1 900.

Application tiled October 14, 1897. Serial No. 655.100. (No model Be it known that I, GUSTAV HILGENSTOCK, a subject of the King of Prussia, Emperor of Germany, and a resident of Dahlhausenon-the-Ruhr, lVestphalia, Kingdom of Frussia, Germany, have invented a certain new and useful Improvement in Coke-Ovens, (for which I have obtained German Letters Pat-ent No. 88,200, filed December 8, 1805, and issued August 27, 1896,) ot' which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to the construction of horizontal externally-heated coke-ovens adapted for saving by-products, and has for its object to provide a better system and arrangement for heating such ovens.

The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which- Figure 1 is a vertical longitudinal section taken through the heating-due between two ovens, as on the line 1 l of Fig. 6. Fig. 2 is a horizontal section on the line 6 6 ot' Fig. l; Fig. 3, a horizontal section on the line 7 7 of Fig. 1; Fig. 4, a horizontal section on the line 8 S of Fig. 1. Fig. 5 is a front view, partlyin section, on the line 2 2 of Fig. 1. Fig. 6 is a vertical cross-section on the line 3 3 of Fig. 1. Fig. 7 is a vertical cross-section on the line 4 e of Fig. 1. Fig. S is a rear view, partly in section, on the line 5 5 of Fig. l.

A A A,&c. ,indicate the coke-ovens, having, as shown, openings at Afor the outward passage of gas. Situated between and extending both above and below the top and bottom of the coke-ovens are horizontal lines, the lower portions of which are divided by vertical walls D, D', D2, D3, D4, D5, D, and DT, Fig. 1, into separate combustionchambers B to B7, the upper portions of said chambers being by means of vertical partitions divided into divisional fines, as indicated at C to C7, all of said lues opening at top into a common flue E, which at one end of the horizontal chamber opens into a downtake E', (shown as divided into separate lues by vertical partitions,) and thence into a chamber F, from which a lateral passage F' leads into a chamber G, from which in turn leads an inclined flue G', which enters the common take-off flue I-I. As shown, the upper portion of the horizon tal flue above the flue-passage E is divided by horizontal walls into a number of vertical passages I, these at one end of lthe structure opening into a horizontal tluc I' and those at the other end of the structure opening into a horizontal flue I2, said lues I' and I2 opening in turn through passages I3 and ILL into conduits I), which by connecting-pipes S, Fig. 6, open into conduits R, which connect through passages A with the ovens. Valves, as indicated at P and R, are arranged, the valve P to close or open the conduit P and the valve R' to`close or open the connection ot' the conduit R with the gas-mains, into which the gases from the ovens are passed when it is desired to save them. It will readily be seen that by properly manipulating these valves the gases from the oven can be turned into the flues I' and I2, from which they will pass down into the various divisions ot the horizontal heating-flue.

J J, the., indicate a series of parallel tunnels constructed in the foundation of the ovens and of su liicient size to permit the passage of a man. They are properly made, as shown, parallel with the ovens and one for each two ovens.

K, Fig. 1, isa connecting-tunnel, into which the tunnels .I open.

L indicates a gas-main extending through the tunnel K and having connecting-pipes L', through which gases pass to a series of horizontal gas-pipes L2, of which two are situated in each tunnel J and from which `burner-pipes L3 lead to each oit the combustionchambers B to B7, entering said combustion-chambers at the bottom, as shown.

Air may be drawn in from the tunnels J by the injector-like action of the gas escaping into the combustion-chambers, or the combustion-chambers can be supplied with air to support combustion in any convenient Way. I have shown air-mains M M, Fig. 1, builtin the masonry at the top of the ovens, where they will receive considerable heat from the hot masonry, said air-mains connecting with IOO air-pipes M', Which in turn connect with and supply air-luesN N, Fig. 6, dac., situated in the masonry beneath the ovens and connecting, as indicated at N', with the combustionchambers B to B7. lt is obvious that the air supplied by this construction Will be quite highly heated before entering the combustion-chambers.

O O O, Fig. l, the., indicate flue-passages leading from each of the combustion-chambers B/ to B'finto lues O', which in turn may connect in any convenient Way (none being indicated) with a take-off flue H. y

The use of the flues O and O', Fig. l, is to provide an exit for gases at the bottom of each combustion-chamber when it is desired to heat the ovens by gases drawn in from the top, as through the passages I3 and I4. When so used, air is permitted to enter with the gases, as through passages Q Q.

It Will readily be seen that by my system of vertical combustion chambers, situated side by side and extending substantially throughout the length of the heating-dues between the ovens,'each being independently supplied with gas, I am enabled to nicely regulate the temperature of all parts of the oven. Moreover, this system permits the heating of the lower parts of the oven to the higher degree, Whichis desirable, and enables me to regulate not only the temperature, but the pressure, upon all parts ot' the oven-Walls, Wherebyl am enabled to prevent toa greater extent than heretofore either the passage of heating-gas and products of combustion into the ovens or the loss of oven-gas by its passage from the ovens into the heating-dues.

The arrangement of the tunnel system beneath the ovens not only places the gas-mains and supply-pipes Where they are not exposed to injury, but permits ot' the easy regulation of the gas-supply to each and every combustion-chamber and is, in fact, a most important feature of the construction illustrated.

The construction by which I am enabled to couple the gas take-oils A R with the heating-fines is advantageous not only as enabling me to use oven-gas for heating the flues, but also as affording means for sucking the gas and smoke out of the ovens when they are opened for charging or discharging, thus protecting the Workmen.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In combination with a series of horizontal externally-heated coke-ovens arranged side by side and having heating-fines arranged in their partition-Walls and discharging-openings at their ends, a series of parallel tunnels of size suflicient to permit the passage of a man arranged beneath the ovens and heating-fines and parallel with the ovens, gas-conduits as L2 running through and accessibly situated in said tunnels and a series of burner-pipes extending from different points along the length of each of said conduits L2 into the heating-dues aforesaid.

2. In combination with a series of horizontal externally-heated coke-ovens having heating-fines arranged in their Walls, a series of vertical partition-Walls as D/ D2 D2, duc., separating the lower portion of said flues into separate combustion -chambers extending substantially from front to rear of the ovens and a series of gas and air conduits entering the bottoms of said chambers and supplying each.

3. In combination With a series of horizontal externally-heated coke-ovens having heating-tlues arranged in their Walls, a series of vertical partition-Walls as D/ D2 D2, dac., separating the lower portion of said tlues into separate combustion-chambers extending substantially from front to rear of the ovens, a series of parallel tunnels of size sufficient to permit the passage of a man arranged beneath and parallel with the ovens, gas-conduits as L2 accessibly situated in said tunnels and a series of burner-pipes extending from each of said conduits L2 into each combustion-chamber.
